Explanation / Answer

1. Anticoagulant is a substance that prevents coagulation. So, the given statement is false or incorrect.

2. Persons with blood type O don't carry any antigen on their RBC membrane. They usually carry the antibodies of A and B antigens in their plasma. So, the given statement is correct.
